Second-hand record stores in Tokyo

Disc Union is a big business with a prominent ground level store front in Ochanomizu. The name is emblazoned on the building in English script. You can’t miss it. They may have smaller branch stores elsewhere in Tokyo.

Many thanks for the quick and informative responses. I will enjoy my day off, I'm sure.

I bought quite a few records from HMV Records and Books in Shibuya and Shinjuku. In Shibuya, the record shop is in a different location than the book shop. Many thanks to ANA for not weighing carry on luggage. ;)

Also, if you’re into chef’s knives, Japan is awesome for those too. We bought knives from Seisuke. Knives go into your check ins of course.

Oh, and I almost forgot, drop by Yodobashi and BIC Camera if you have time.

Have a great trip!
